Board has issued a warning that "major loss of life" is likely to result from future accidents, urging the U.S. and Canadian governments to develop new safety rules. While many in the fossil fuel industry as well as supporters of the Keystone XL pipeline are using the critique of the safety of crude-by-rail as a reason to push for more oil pipelines, critics such as climate expert David Suzuki say both transportation methods pose significant risks. The NTSB’s recommendations, which were coordinated with the Transportation Safety Board of Canada, included re-routing trains that carry hazardous materials, such as highly explosive North Dakota Bakken crude oil, to avoid populated and sensitive areas. "The NTSB is concerned that major loss of life, property damage and environmental consequences can occur when large volumes of crude oil or other flammable liquids are transported on single train involved in an accident," NTSB said.
